A laser is like a super-powered flashlight. Imagine shining a tiny beam of light that doesn’t spread out, it stays narrow and bright, just like the beam from a flashlight but much stronger. When you use a laser in an eye exam, it’s like a little light that can show the doctor exactly what's going on inside your eyes. Lasers are used in many places because they're precise and powerful.
Examples
- Lasers are used in barcodes to scan the lines on packages quickly.
- Dentists use lasers to remove small parts of teeth without hurting patients much.
